Properties

drawCurlPosition

val drawCurlPosition: Boolean

Flag for rendering some lines used for development. Shows curl position and one for the direction from the given position. Comes handy one playing around with different ways for following pointer.

drawPolygonOutlines

val drawPolygonOutlines: Boolean

Flag for drawing polygon outlines. Seeing polygon outlines gives good insight on how original rectangle is divided.

drawShadow

val drawShadow: Boolean

Flag for enabling shadow rendering.

drawTexture

val drawTexture: Boolean

Flag for texture rendering.

shadowInnerColor

val shadowInnerColor: FloatArray

Inner color for shadow. Inner color is the color drawn next to surface where shadowed area starts.

shadowOuterColor

val shadowOuterColor: FloatArray

Outer color for shadow. Outer color is the color the shadow ends to.

texturePage

val texturePage: CurlPage

Contains texture and blend colors for a page.

Functions

curl

@Synchronized

fun curl(curlPos: PointF, curlDir: PointF, radius: Double)

Sets curl for this mesh.

onDrawFrame

@Synchronized

fun onDrawFrame(gl: GL10)

Renders out page curl mesh

reset

@Synchronized

fun reset()

Resets mesh to 'initial' state. Meaning this mesh will draw a plain textured rectangle after call to this method.

resetTexture

@Synchronized

fun resetTexture()

Resets allocated texture id forcing creation of new one. After calling this method you most likely want to set bitmap too as it's lost. This method should be called only once e.g GL context is re-created as this method does not release previous texture id, only makes sure new one is requested on next render.

setFlipTexture

@Synchronized

fun setFlipTexture(flipTexture: Boolean)

If true, flips texture sideways.

setRect

fun setRect(r: RectF?)

Update mesh bounds.
